The basic subtle meaning is "not obvious": something subtle is small, quiet or delicate enough that you might miss it unless you pay attention, like a subtle hint of lemon in a cake or a subtle change in someone's tone. The word can also describe a person or method that is clever in a quiet, indirect way.
Alongside the adjective you get subtlety as a noun and subtly as an adverb. All three keep a b that is never pronounced, which trips up many spellers. What follows covers its senses, its history and its correct spelling.

Subtle definition and the silent b
The subtle definition in most dictionaries begins with the idea of fineness, and that comes straight from its history. English took the word from Old French soutil, which came from Latin subtilis, "fine, thin, delicate." In Middle English it was usually spelled without a b, as in sotil.
Later, scholars who admired Latin put the b back into the spelling to show the word's Latin parent. The pronunciation never changed, so the b has stayed silent ever since. Debt and doubt went through a similar respelling.
Subtle vs obvious, and other near words
| Word | Meaning |
|---|---|
| Subtle | Quiet, slight or delicate; easy to miss |
| Faint | Weak or barely there, without the sense of cleverness |
| Nuance | A small shade of difference in meaning or feeling (a noun) |
| Vague | Unclear because details are missing, not because they are fine |
| Obvious | Easy to see or understand; the usual opposite |
| Blatant | Very obvious, often in an annoying or shameless way |
Nuance and subtle often travel together: a nuanced argument notices subtle differences. Sarcasm, by contrast, can be subtle or blatant depending on the speaker.
How to use subtle well
You can place subtle in front of a noun (a subtle flavor) or use it after be, seem or look (the change was subtle). Comparatives are subtler and subtlest, though more subtle and most subtle are also correct and very common.
Popular pairings include subtle hint, subtle difference, subtle shift, subtle humor and not very subtle, which is a playful way to say something was obvious. The noun subtlety (SUT-l-tee) can be uncountable, "she spoke with subtlety," or countable, "the subtleties of a language."
Spelling tip: write the b in all forms. Subtley without the second e is a common mistake; the correct adverb is subtly.
